768kbps is significantly worse than AC3 with 640kbps and you demanded 1/4 full DTS bitrate - by principle DTS is more close to lossless FLAC than AC-3 (however DTS is kind of lossy FLAC) - go for 384 or better 448kbps AC-3 if your goal is quality and reduced bitrate and compatibility, if compatibility is not your goal then go for AAC with 384kbps - avoid DTS if you not wish spent for audio at least 1411.2kbps - simply with lower bitrates DTS is unable to provide high quality (don't ask why so many people insist to use lower bitrates with DTS and their claim superior to AC-3 quality - this is completely wrong). Conversion is not copy, desired by you bitrate is not supported by DTS (and in fact DTS with half bitrate i.e. map 0:v -map i:0x89 -strict -2 -c:a copy -ac 6 -b:a 384k -ar 48000 -hide_banner 'Pulp_Fiction.mp4' Ok then at this point I wonder, he copied, what he copied ?, he copied the DTS codec, is for what reason if I manually set the audio codec (dca) the conversion goes me error, I am convinced that it is an internal error of the codec (dca) in FFmpeg.

I think the problem is the internal codec (dca) in ffmpeg, I hope will solve in the future, for the moment if no one else has given a valid answer to the problem, I think it is useless to clog the thread with useless answers. Ha.Ha.Ha.Yes, but I did not ask you this, I did not open the thread with the problem that the audio stream encoding in DTS was low quality or it was disgusting, asking for a solution, in fact I told you that it was not the problem, if you reread my first post another 10 times maybe you'll understand the problem. I said and I meant that encoding a 5.1 stream to DCA at 384kbps will probably suck very much.īut, since you are a functional illiterate, be welcome to my IgnoreList. I DID NOT SAY and I did not mean that 'it's a bitrate problem'. If the problem is ffmpeg and the internal codec dca, I'll have to do without it, at this point I do not care about a DTS with mono or stereo audio track, it is not convenient to use it for conversions. I do not think it's a Bitrate problem, in fact it is not, I use the FFmpeg 3.4 version of, personally the most stable version for my needs. Regardless of bitrate and sampling frequency. dts files generated by dcaenc and ffdcaenc have been validated by the program DTS-HD Stream Tools, Tiny subset of the full DTS-audio specifications.»ģ) all the. Much in the same way the official /certified DTS encoders do not go beyond a «it's not impossible that the hardware-based DTS decoders are 'crippled' somehow, «this encoder uses only the most basic compression techniques defined in the DTS specification,Īnd thus cannot win any comparison with commercial DTS encoders.» For what it's worth,ġ) quoting the author of the original source-code of dcaenc:

The problem is the result of a design flaw in the firmware, since the same elementary streamsĪre decoded without audible distortion by the software DTS decoders on a PC.
